The Add and Modify windows of the Protocol VLAN Group hold the following fields to be configured:
Parameter Description
Group ID (1-16)
Enter an integer from 1 to 16 to identify the protocol VLAN group being created here. For the
Modify window, this field will display the Protocol Group ID number of the group being configured.
Action
Use the drop-down menu to add or delete the protocol to this group. This protocol is identified
using the following Protocol field.
Protocol
Use the drop-down menu to select the frame type to be added or deleted from this profile. The
frame type indicates the frame format. The user has three choices for frame type:
• Ethernet II – Choose this parameter if you wish this protocol group to employ the
Ethernet II frame type. In this frame type, the protocol is identified by the 16-bit (2 octet)
IEEE802.3 type field in the packet header, which is to be stated using the following
Protocol Value.
• IEEE802.3 SNAP – Choose this parameter if you wish this protocol group to employ the
Sub Network Access Protocol (SNAP) frame type. For this frame type, the protocol is
identified by the 16-bit (2 octet) IEEE802.3 type field in the packet header, which is to be
stated using the following Protocol Value.
• IEEE802.3 LLC – Choose this parameter if you wish this protocol group to employ the
Link Logical Control (LLC) frame type. For this frame type, the protocol is identified by the
2-octet IEEE802.3 Link Service Access Point (LSAP) pair field in the packet header,
which is to be stated using the following Protocol Value. The first octet defines the
Destination Service Access Point value and the second octet is the Source Service
Access Point (SSAP) value.
Protocol Value
Enter the corresponding protocol value of the protocol identified in the previous field. This value
must be stated in a hexadecimal form.
Click Apply to implement changes made.
